A plow carrying structure comprises be: ms 13. which rigidly seeurctl together in spaced relation at their front ends by brackets 14, l5lllt'l a. cross her it and at their rear ends by brackets 17. A plowshare 12 is regidly secured. to each locum l3. The plow illustrated in the drawings comprises gang of three plows, but it will he unclerstood that any desired number of plows may be employed.

The front end of this plowcarryingstructure is :idjustably sustained-by two crank axles 23 and. 24: which are edeptecl to serve as lifting connections for the sides of the structure respectively. Axle is pivoted in the furrow-wlieel and is comlectetl to the plow-supporting structure to sclj net the plows carried by the structure relative to the ground. by swinging the axle about its axis in the furrow-wheel. Axle 24 is pivoted in the land wheel. ancl also pivotally connected to the PlOWfilljJPOllllllg structure. These crank-axles 23 and 24% which are jourmailed in brackets 27. 28 s ot 29 "hieh are respectively secured to the plow are disposed one in froiit of the each extends transversely across carrying structure.

The rear end ofthis structure is sustained by a standard. 18 which. has runner ill at its lower encl adapt-ed to travel. on the ground, "the standard being slidohly held in a sleeve 2i) which is rigidly secureil to one of the plow-beams 13 by hers .511 and 22. The rear end of the plow' iey be adjusted relatively to the ground, by e.- lever 30 which is pivoterl to one of the bars and is connected to :1 standard 18 by linh 31, a stop 32 for lever 30 being provided onorie of the bars 521 when it is inone oifitsolt rnativepobeams 13,

the plow- Qsitions. Link 3i. has upper end pivoted to a collar 33 which is held. on standard 18 by pins above and. below the collar respecother and Fig. 9 is a similar View showing the isin the position shown in Fig. 2', the relation connection. A

which serves as a traction-wheel for driving this mechanism. A sprocket-wheel is suitably-secured to the hub of the land Wheel which is mounted on the inturned spindle 36 of arch axle 24. A collar 37 on said spindle, holds the landwheel and sprocket on the spindle. This sprocket serves to drive a chain 88 which extends around a sprocket wheel 39 which is loose on crank-axle 24 and has integrally formed therewith a clutch or ratchet-wheel 40 which will be constantly driven when the plow is in operation. These sprockets and chair. serve as power-mecha- .nism for shifting the cr' k-axles to' raise the plows. A tightener 4'1 forchain 38 mounted. on an arm 42 which is secured a to. shaft 24.

Wheel 40 is adapted to operate a dog 43 which is pivoted as at 44 to a -collar or carrier 45 which is pivoted on shaft 24. Said collar or carrier is connected by a, link 46 '1 pulled, will operate carrier 45 around axle 24 to shift link 46 which will operate arm 47 to rock axle 23, and thus raise and lower the front end of the plow-supporting structure. Rotation. of axle 24 about its axis in wheel 26, will cause the front end ofthe plow-carryingestructure to be raised or lowered according to the direction in which the axle is operated.

Axle 24 axle 23, by an adjustable connection. between said axles which serves as adjusting-mechanism for the land-wheel relatively to the furrow-wheel. This connection comprises a segmental rack 49 which is rigidly secured to axle 23, a lever 50 which is pivoted on said shaft and adapted to be locked to said segment in different positions by a springpressed bolt 51 which is releasable by a nger-lever 52 on lever 50, and arm 53 which is rigidly secured to shaft 24 and a link 54 between said means of this connection between said axles, the power-operated rock axle 23 by means of dog 43, collar 45,

armand lever 50. B

lifting-mechanism will link 46 and arm 47, and axle 24 will be simultaneously rocked by means of segment 49 lever 50 and link 54 both of the arch-axles ppwer to raise both sides of the plow-supand arm 53, so that porting structure and the plows carried is connected to be operated by will be operated by.

thereby, out of the ground. By adjusting lever 50 along rack 49, axle 24 will be rocked -to raise or lower the land-wheel relatively to the furrow-Wheel. A spring 55 connected to lever 50 and rack 49 holds the rack in yielding but connected relation to the lever during adjustment of the lever.

oppositely extending arms 56 and 57 are secured to shaft 23 and counter-balance springs 58 and 59 are applied to saidarms to aid in lifting, and to cushion the lowering operations.

The mechanism for controlling dog 43 to render the draft-operated lifting-mechanism operative and inoperative comprises a slotted cam 60 which has its front end pivotedto one of the bearings 27 as at 61., and its opposite end connected .by a link 62 tog'tn arm 63 on a controller-shaft 64. vA segmental. slot ,65 in cam 60 is formed to guidestud 66 on dog 43 which rides in said slot, and when the dog is shifted by movement of the cam about its pivot 61, with the dog in its lowered position, the dog will be shifted into engagement with ratchet 40 and will remain in engagementtherewith until stud 66 is operated to disengage the dog by cam-surface 67 on the upper end of slot 65. Controller-shaft 64 has an arm 68 which is; connected by a link 69 to a slidable lockholding and releasing-bar 7 0 on a forwardly extending lowering-lever 71, which is fulcrumed at 71". Link 69 may be operated to operate controller-shaft 64 by a rod 72 which is connected to link 69 and to a controller-lever 73 which is pivoted to the front end of lever 71, as at 74. Link 69 is also operatively connected to the releasing bar by rod 72. When the plows are lowered in the soil and it is desired to raise them by the draft-operated mechanism, the operator will push the lower end of lever 73 backwardly which will pull rod 72 forwardly and cause link 69 to rock shaft 64- so that arm 63 on said shaft will operate link 62 to swing cam 60 into position to cause dog 43 to pass into engagement with the rotatingratchet 40.

Lever 71- is provided to lower the plows manually and raise them .if so desired, and is adapted to be locked to a rack 75 which is secured rigidly to one of the plow beams, by a spring-pressed bolt 76. \Vhen lever 71 is locked to rack 75 .both of the axles 23, 24,

. will be locked against rotation and will thus y secure theplow-carrying structure.

-Lever 71 is connected to operate axle 23 by a link 87'which is pivoted to said lever at 88 and to an arm 89 integral with segment 49. A finger-lever 90 on lever 71 1s 'connegtedto bolt 76 bya rod 91 so that the lever 71 can be released from segment 75-- and then operated to operate axles 23, to raise or lower the plow-supporting structure. When the plows are in raised posi 1O ually operating shaft mechanism for the pow rendered operative.

plow has force said bolt into notch messes tion, as shown in Fig. 2, and it is desired to lower them, it is only necessary to operate finger lever 90 to release bolt 76, lever 71 and the raising andlpwering connections will be free to permit the weight of the plows to lower them or, it necessary, pressure may be applied to lever 71., It will be observed that the link 87, aside from serving as an operative connection for man- 23 to raise or lower the plows, serves, when lever 71 is locked, .to lock axle 23 against rotation and also axle 24 because it is locked to axle 28. When lever 73 is shifted to operate the controllingirig-mechanisrn, rod 72 wil also operate our "all which is slidablv mounted on lever 71 and ex tended into osition to releasebolt 76 at the [time that t e -poww-lifting mechanism is When bar 1 0' is thus shifted, a..,-hole 80 therein. will brought into position to permit a laterally sliding spring-pressed bolt 81 to pass intosaul hole andlock said bar 70 into position to hold 25 bolt 76 released, until bolt 81 is withdrawn from engagement with bar 70 by en in; clined releasing earn 8d which is lined to one of the plow beams and is formed to withdraw bolt 81 from bar 70 when the been raised. During the lifting operation, bolt 81 holds bar 70 to release bolt 76 from rack 7 5, and at the end of such an operation, bolt 81 will release bar 70 to permit a spring 85 applied to bolt 76 to 75* of segment 75 and lock the arch-axles in raised positions. will not be held in released position byehand will be independent of bar 70, because the v 40 latter will become operative only when controller-lever 733s operated to render the draft-operated lift ng-mechanism operative. The operation of the improved plow 1s JFollows: assuming the parts'to be in position shown in Fig. 2, at which time the plows will be elevated or raised out of the ground,

and it is desired to lower the plows, lever 30, Wlll be swung into position indicated m Fig. 1

8 to raise the runner 19 above the ground,

so that the plows will be free to be raised andlowered without interference from the runner. This lever 30 may be left in this position during the operation of the plow in the field end is usually rendered operative only when the plow is being transported.

To lower the plow, the operator will press fingenleverfil) toward the handle of lever 71 to cause rod 91 to operate lock-bolt 76 against the force of spring 85, and to withdraw the bolt from the notch 75 in rack 7 This unlocking of belt 76 occurs, independently of the controlling-mechanism for the draftoperated lifting-mechanism. The weight d the plows will cause the arch M axles to swing in the carryingv heels rcwhereupon Bolt 76 when shifted by lever 90,

'23, 24 by means spectively, under control of lever '71. The latter lever swinging about its fulcrum 71 will control the oscillation of the arch'axles of link 87, arm 89, segn'ient 4-9, lever 50, link and arm Upon release of lingerdever 90, when the plows have been lowered, loclobolt 76 will pass into one of the notches 75 in rock 75 and will lock lever 71 and its connections, so that both of the arch-axles will be locked against oscillation. If necessary, lever 50 may be adjusted relatively to rack ll), to give the plows and furrowwheel the desired depth in the soil relatively to theland. By adjusting lever 71in the dill'erent notches of rach'lo, the depth oi the plows may also be varied.

"iihen i owing, parts will be in posil v vi b tron shown in 1- ig. 5 oi the drawings. lVhen 70.. The operation of bar 70 will release bolt 76 from. rack and thus release the lever 71 and the connections for locking the structure in lowered position. Shaft (3 1 will also roe-l; arm 68 and operate link 62 to cause slotted guide (50 to shift stud 66, so thatdgg l3 will pass into operative engagement with the ratchet l0.v The latter will rotate and operate dog 43 until stud 66 passes into the upper portion of slot 65 when it will be withdrawn from the ratchet. A slot 62 formed in. cam 60 to provide a loose 4,;- nection for link 62 to cause bar 70 to release lever 71 and its connections before the draft-operated lifting-mechanism is rendered operative. lVhen dog 43 is operated by ratchet 40, it 'will rock arm e15 on axle leased lock-bolt 76, bolt 81 will pass into hole in said bar and lock this holding and releasing bar in position to keep bolt 76 re leased from rack 75 until the cam S lof the plow-carrying structure engages bolt 81. and withdraws it from bar 70. This release occurs when the bolt 76 reaches the notch 7 7r which is adapted to lock the lever in position assumedwhen the plows are raised. During the lowering of the plows, the controlling-mechanisrn, including shaft (34, link 69, link 62 and cam 60, remain in normal relation so that the releasing and holding bar 70 will not be operated to release the lock-bolt 76. ll'hen bolt 81 withdrawn from hole 80, in bar '71, by com 84. spring 85 in forcing bolt'76 into the notch 75, will frame and the act upon bar to'restore the controlling mechanism to its normal position and then it will be in readiness for a subsequent op,- eration. I

The operating mechanism for the lifting connections exemplifies one in which power In the operation of the connection be-' tween the shafts 23 and 24: of the crank connections, the inner portion of lever 50 between the lock 51 and crank-axle 23 operates as an adjustable arm by which the relative position of the two lifting connections may be adjusted.

' The invention set forth which'the plowshare is rigid with a carry ing-structure which comprises members or beams fixedly secured together in spaced relation and whichis directly supported by lifting connections between the sides of the land wheel at one side and a furrow wheel at the other side and the invention exemplifies a plow of that type in which the lifting connections for the sides of the frame are connected together by suitable means so that the power lift mechanism will operate both of the lifting connections through the connecting means to simultaneously raise both sides of the frame.

It will be observed that the crank axles are shifted differentially by the power operated means and as a result the bottoms of the plow bodies are kept in substantially horizontal alinement, both when the plowsare, lowered and when they are raised, vthe differential movement serving to compensate for the additional movement necessary to bring the wheels which are at different elevations when plowing to the same elevation relatively to the frame when the plows are raised. I

The invention is not. to be understood, as restricted to the detailsset forth, since these may be modified by the skilled mechanic within the scope of the appended claims without departing from the spirit and scope of the invention.
